UNITED STATES PATENT OFFICE.

BENJAMIN It. HAND, OF OAMDEN, NEW JERSEY, ASSIGNOR OF ONE-HALF TO GEORGE A. MUNGER, OF SAME PLACE.

CUTTER-HEAD.

SPECIFICATION forming part of Letters Patent No. 327,392, dated September 29, 1885.

Application iiled May 21, 1885.

To all whom t may concern.-

Beit known that I, BENJAMIN R. HAND, a citizen of the United States, residing in the city and county of Camden, State of New Jersey, have invented a new and useful Improvement in Gutter-Heads for W'ood-Working Purposes, which improvement is fully set forth in the following specification and accompanying drawings, in which- Iiigure l represents a top or plan view of'a cutter-head embodying my invention. Fig. 2 represents a section in line x x, Fig. 1. Fig. 3 represents a horizontal section in line y y, Fig. l.

Similar letters of reference indicate corresponding parts in the several figures.

The object of my invention is to reduce the expense of the cutters or blades of cutter-heads and adapt the same to be firmly held in position on said heads.

Referring to the drawings, A' represents the cutter-head, and A represents a clamp or clamping head or plate, between which a blade, B, is iitted and by which it is held.

The inner face of the head A is recessed to receive the blade B, and the backof the blade abuts against the shoulder C, as formed by Said recess.

D represents screws, which are tapped in the head A, and have their points or inner ends in contact with the back of the blade, said screws being adapted for adjusting the blade with precision in relation to the front ends of the heads A A', the heads of the screws being conveniently accessible at the outside of the head.

E represents the screws for connecting the heads and clamping the blades between them.

It will be noticed that the blade rests flat against the inner face ofthe head A', and is made narrow instead of extending the entire dimensions of said head, and as the cutting-edge of said blade has all the advantages of a blade of the size equal to that of the head, it is evident that there is a considerable saving in the expense of blades. Furthermore, the blade is not slotted or perforated, whereby there is economy in the manufacture thereof (No model.)

in this respect, and it is strong and durable. It will also be seen that the blade is firmly held between the two heads, owing to the screws E, and is thereby prevented from shifting after it has been properly set or adjusted.

Vhen the blade is worn or dull, it may be readily removed, sharpened, or ground, and returned to its normal position, the points of the screws D serving as abutments for the back of the blade, so that the blade cannot shift inwardly. lIhe screws E clamp the heads together, whereby the blade is again rmly held, as has been hereinbefore described. 'Ihe dowel-pins F (shown) assist to prevent the shifting of the heads and properly locate one head on the other.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-

l. The blade B, in combination with the clamp A, having its inner face recessed and provided with a shoulder, in combination with adjusting-screws D, working in said recessed face of the clamp A, and having their points in adjustable contact with the back of the blade, substantially as described.

2. The blade B, in combination with the head A', the clamp A, securing the said blade to said head, the clamping-screw E, passing through the said clamp AV into the said head A', and the dowelpins F, secured to said clamp A, and entering in recesses in said head A', substantially as and for the purpose set forth.

3. The head A', in combination with the narrow blade B, clamp A, having its inner face recessed and provided with shoulders C, the said clamp A being secured to said head A' by screw E, holding said blade in position, screws D,working in recess in said clamp A, and having their points in adjustable contact'with the back of blade B, and dowel-pins F,.attached to said clamp A and resting in recesses in head A', substantially as described.
